I installed a Central Boiler back in December. I made a 5"+ diameter hole in my poured basement wall for the termo-pex to enter the house. The hole is very rough as it was done w/ a carbide drill & knocked the core out w/ a sledge hammer & chisel.
Anyway, what is the best thing to use to seal this area? I used roofing cement, the kind that will adhear to wet surfaces, and I still have a leak. Maybe i need to dig it out again & try to cram more of it in the hole from the outside, now that the inside is "set".
What do you guys use?
